Tachemeter? Telemeter?

[Foxer55]

Looking to buy a watch rather quickly as my Rolex must go back to teh shop. I've been looking at some recent Hamilton chronographs but am cionfused. What appears to be the typical Hamilton chron has a tachymeter scale on the bezel, however, there are Hamiltons being sold that have a telemeter scale on the bezel. These watches are hard to come by and I'm trying to get the tachymeter version...tachymeter does not equal telemeter. I don't know if this is a manufacturing variance, a product center variance, or are they frauds? Anyone know what's going on with this?

From what I have seen the aviation models use the tachymeter and the field models use the telemeter. I suppose the rationale is that when you are flying you would want to know your speed. When you are facing mortar fire you want to know how far away the mortars are. If you actually had to fly away from mortar fire I don't know what you would use.

He-he. Good answer. Thanks.
